Parallax

Developed within The Shake, Parallax begins with the precise void separating the outstretched hands of Maurice Harron’s Hands Across the Divide. In two videos, this absence is rendered as a translucent, reflective digital volume drifting across separate views of Derry~Londonderry.

As it passes over buildings, streets, and murals, its warped surface bends, partially obscuring the city beneath it. The gap becomes an optical device: division does not merely occupy the landscape but reorganises how that landscape is perceived.

The volume moves continuously back and forth between the two screens, each corresponding to one of the city’s historically divided communities. Neither side retains it; the same absence is repeatedly transferred from one view to the other. Parallax names this instability: the unresolved past becomes a shared structure of perception, altering both views without allowing them to settle into a single image.
